Transpiration

Front

What are xylem tubes made of?

Back

Xylem tubes are made of dead cells.

Front

What happens to the rate of transpiration in dry air?

Back

The rate of transpiration increases in dry air.

Front

How does increasing temperature affect transpiration?

Back

Increasing temperature increases the transpiration rate.

Front

What is the effect of K+ deficiency in guard cells?

Back

K+ deficiency in guard cells makes wilting more likely and decreases photosynthesis.

Front

What type of cells are xylem?

Back

Xylem cells are a type of vascular tissue responsible for water transport.

Front

Define transpiration.

Back

Transpiration is the process of water movement through a plant and its evaporation from aerial parts, mainly leaves.

Front

What role do guard cells play in transpiration?

Back

Guard cells regulate the opening and closing of stomata, controlling water loss during transpiration.

Front

What is the relationship between humidity and transpiration rate?

Back

Higher humidity levels decrease the transpiration rate.

Front

Explain the significance of transpiration in plants.

Back

Transpiration helps in nutrient transport, cooling the plant, and maintaining turgor pressure.

Front

What factors can affect the rate of transpiration?

Back

Factors include temperature, humidity, wind speed, and light intensity.
